Seen a few posts about this on here, but all are PC based and I'm not confident the resolutions are applicable.
Here is what is happening:
We've got 4 edit bays. Identical MacPro 12 core towers. All with the Nvidia/PNY Quadro 4000 for Mac GFX card. In the past month, 3 out of 4 inexplicably have lost the ability to use the Mercury Playback GPU. We've had to go straight software at this point.
We've gotten the 'missing renderer' error and nothing we attempt seems to fix it. Even a complete wipe of an edit system, reinstall of OS, drivers and Adobe suite won't fix it. Once it's gone, it's gone.
We've not been able to establish any pattern to this either....the error has popped up on two computers about two weeks ago with no rhyme or reason. It popped up on a third yesterday immediately after we installed Avid Media Composer.
All of these computers are running the most current Nvidia Drivers, Cuda driver, Premier 6.03 and Mountain Lion. They've worked for a month or so, but in the past 2 weeks, they've all started falling and are unable to recognize the Nvidia card as the renderer.
Can anyone help? This is really frustrating!
